Ubuntu 20.04.3 LTS Cannot Build From Source #25

Open agoessling opened 2 years ago

agoessling commented 2 years ago

When following the instructions in the README to build from source, during the python setup.py install step I get a cmake error complaining about several missing dependencies (cppyy, libcling, libclang):

After manually installing cppyy (pip3 install cppyy), the error only complains about libclang:

There are some clues in .github/workflows/build.xml I'm having a play with this, and for the moment using act to run the github build workflow locally, in docker.

I think the ubuntu instructions need fleshing out.

I got a little further in Ubuntu by adding 11 as a version to the src/cmake_modules/FindLibClang.cmake

I eventually got stuck with this error, it's all a bit hard to debug TBH as I mostly do python dev + not native.
